useful Improvements in Firearms, of which the following is a specilication.

This invention relates more especially to that class of firearms usually designated as small arms, and a principal object of the invention is to furnish an improved firing train `mechanism and grip-safety device particu- One class of small arms to which my pres-Y ent improvements are applicable includes the auto-loading pistols having a grip-stock or handle 'portion of the frame or receiver of the firearm, which is adapted to-receive a safety device operable by hand grip or compression. I'

An improved auto-loading pistol of this kind is described in my Patent No. 1,348,733, dated August 3, 1920, and granted on my copending application (renewal) Serial No. 311,689, filed July 17th, 1919. Therefore, for convenience ofillustration, I have herein shown mypresent improvements as arrangedand applied to the particular kind of autoloading pistol shown in the drawings of said patent, to' which reference may be had.

The features of my firing train mechanism and grip-safety device are that it is a-liring train mechanism and a grip or handle contained safety device arranged to prevent firing of the firearm by locking the firing mem-A vber or hammer and the trigger sear when the grip-operable or grip-safety portion of my device is in normal orsafety position.

. Also, where the firearm is provided with a main slide comprising a firing-pin, to prevent discharge of the firearm by locking the main slide of the firearm to prevent eli'ective contact between the liring-pin and the cartri dge, so that action of the firing member or hammer on the firing-pin will not explode the cartridge.

Another feature of my invention is that it is a firing train mechanism and grip-safety device so organized as to effectthe locking of the main slide of the firearm in forward position by means of a combined slide-detainer and controller which engages a face on the main slide that is rearward of the block-abutment face of the frame of the firearm for retarding the breechblock in its rearward acs Specification of Letters Patent.

Similar reference characters or numerals` referto similar parts throughout the several views.

The firing train mechanism and gripsafety device is herein described and shown as applied to a pistol provided with a main slide anda breechblock comprising a firing pin. The pistol in the present embodiment of my invention is provided with a main slide C and with a rigid breechblock E. comprising a firing-pin P, the force of the powder gases being first exerted upon the breechblock E to move it/ rearwardly and transmitted thereby, without the use of any intervening spring or yielding device, to the main slide C to move the main slide rearwardly. The breechblock E is retarded in its rearward movement byengagement with the frame or receiver B of the pistol, changing position or rising by engagement of the face 51 with the face 2f, during which period there is retardation of the breechblock E relative to the main slide C, as at the face 31 and face 5d, while the main slide moves rearwardly, and the breechblock then moves rearwardly concurrently with the main slide C, until the main slide has reached its most rearward or retracted position. This change of position is accomplished by means of a face 8k on the breechblock E which engages a block-lifting actuation face, herein shown as a ribface 33f, on the main slide C, and the position ofthe breechblock E, is thereby changed and the breechblock moved and locked tothe main slide to afford concurrent movement of the breechblock E with the main slide C after rearward movement of the breechblock itself has been retarded by said engagement with the frame or receiver of the pistol. The retardation of the breechblock E before mentioned, relative to the main sli-de C, is causedlby the engage- `Inent lof the face 5d with the face 31. as the breechblock E is retarded in its rearward movement by engagement with the frame of the pistol as before stated and changes its position.

The firing member or hammer H is pivotally supported on the grip-stock of the pistol and is movable to firing position and to fired position. The firing member H is moved from fired position to firing position or cocked position by engagement of the rear-face 10, of the main slide C of the pistol with the forward face of the firing member or hammer H, as the main slide C is 1moved rearwardly to its most rearward position; or the firing member or hammer H may be moved to firing position or cocked by a suitable roller arranged on the main rslide C to engage the firingmember or hammer when the main slide is moved to rearward position, or may be moved to firing position or cocked by any suitable means.

The firing member or hammer H is provided with a firing notch or cock-notch 81,

and with an eccentric cam face 8k, the gripstock of the pistol being bored out or otherwise suitably cut away, as at 2S, to receive the tiring member or hammer and theY various parts of my invention, The sear member S is pivotally supported on the gripstock of the pistol and is provided with a locking shoulder 171 which is engageable with the cock-notch 81 of the firing member orhammer H, and is provided with a face 17 which' is engageable with the eccentric cam face 8k of the firing member or hammer, and is provided with Yan arm S10 and with an end-'face 17,". A spring actuated contactor 11 is arranged on the rear side of the searmember S, having a nose or plunger-12, which engages a face 13, arranged to the rear of the cock-notch 81 on the firing member or harnmer H to force or move-the end-face 17d of the sear member S downwardly when the firing member or hammer H is moved to fired position, Fig. 5. i

The slide-detainer and controller N is slidably movable in a guideway 14, milled out or otherwise provided in the grip-stock of the pistol,-but any other suitable means for guiding the slide-detainer and controller in its movement may be employed. The slidedetainer and controller N is engage-able at its upper end 14a with the rear face 10 of .the main slide C of the pistol 'to prevent rearward movement of the main slide, and

preferably is of curved form to facilitate the engagement of the'end 14a thereof with the rear-face 10 of the main slide C. The slidedetainer and controller N is provided with a shoulder 14p having an upper surface 1 4 Iwith which the arm S10 of the sear 'member The actuator 14m is supported by a bracket 16 mounted on the grip-stock of the pistol, and comprises a nose-piece or plunger 17 and a spring 18. The bracket 16 isl bored out to receive the spring 18 and the nosepiece or plunger 17, the spring 18 being seated in the bracket 1G and abutting the lower end of the nose-piece or plunger, the tendency or pressure of the spring 18 being upward. The upper end of the nose-piecev or plunger ,engages the end-face 15 of the slide-detainer and controller N, the purpose of the actuator 14' being to push or force the slide-detainer and controller upwardly.

The grip-operable or grip-safety member G comprises a base-portion G and a connecting rod G2, the base-portion G being attached to the grip-stock of the pistol by a pivot-pin g. The connecting rod G2 is pivotally attached, or hinged, at its lower end, as at 19 to the upper end of the base-portion Cr of the grip-operable or grip-safety member, and is provided at its upper end with a point and enlargement 20, which engages or is received in a hole 21 in the frame of the pistol. the pointed end being permitted a slight upward and downward play or movement in the hole 21 which movement or play is controlled by the adjacent enlargement of the end of the rod. The grip-operable or grip-safety member G is provided with a locking-prong 7 which is engageable with the bottom-side or bottom-face 14 of the slide-detainer and controller N. Thegripoperable member G is yieldable or hand compressible and closes the space 2S formed in the grip-stock of the pistol. The base-portion G of the grip-operable or grip-safety member G is bored out or otherwise suitably arranged to receive the 'main spring or ring-sprin 8", and the movable member or cupped p unger 8c, provided with a downwardly extending spindle or stem`22. The spring 8e is seated in said bored out portion and abuts the under side of the movable member or cupped plunger 8c and surrounds the spindle or stem 22, the tendency or pressure of the spring 8 being upwardly. The connecting rod 8b is pivotally attached at its up er end to the firing member or hammer by a pivot pin 23, a mortiserecess 24 being provided to receive the circular end of the rod 8b. The lower end of the rod 8b is rounded and is seated in the cupped portion of the plunger 8c to provide a ball and socket engagement or movement between the rod 8b and the cupped plunger 8c.

The trigger member F is received in the slot 15 of the slide-detainer and controller N and is movable forwardly by means not shown, and by pull thereon is movable rearwardly. The trigger member F is provided at its inner end with an inclined face 26 which is engageable with the end-face 17 d of the sear member S. y

In operation: The slide-detainer and. controller N being in position for blocking the main slide C from rearward movement, and also locking the sear member S and firing member or hammer H in firing position, and the grip-operable or grip-safety member G being non-grip-compressed and in position of safety, and thereby blocking or locking the slide-detainer or controller in its locking position` Fig. 1, grip-compression of the gripoperable or grip-safety member G releases the locking prong 7b thereof from engagement with the bottom-side or bottom-face 14 of the slide detainer and controller N, thereby permitting downward movement of the slide-detainer and controller from its locking position, Fig. 4. Pull upon the trigger member F engages the inclined face 26 thereof with the end-face 17d of the Sear member S and moves the said end-face rearwardly and upwardly, the contractor ll. being retracted and the locking shoulder 1T being disengaged Jfrom the cock-notch 8" of the tiring member or hammer H, thus permitting movement of the firing member or hammer to fired position. member or hammerHis moved to fired position by the spring Se, the eccentric cam face 8k of the firing member or hammer engages the face 17 of the sear member S, and thereby moves the arm S10 of the sear member downwardly, which arm engages the face 14e of the shoulder 14p of the slide detainer and controller N and thereby bears down or moves down the slide-detainer and controller against the compression of the actuato 14m, and the pistol is discharged, Fig. 5, th" slide-detainer and controller already having been released by grip-compression of the grip-operable or grip-safety member G for downward movement, as before stated. Movement of the firing member or hammer H from red position to tiring position disengages the eccentric cam face 8k from the face 17" of the sear member S and permits movement of the Sear member upwardly. Through pressure of the actuator 14m the slide-detainer and controller N is moved upwardly, and the sear member S is moved up- As the firing wardly until .the'locking shoulder 17b of Aend 14 thereof lies in the path of the main slide C of the pistol and locks the main slide at its rear-face 10 against rearward movement, the slide-detainer/'and controller being blocked or locked in this locking position by the grip-operable or grip-safety member G as later explained.

An important and elicient feature of my invention is that when the firing member or hammer Hand sear member S are locked in firing position by the slide-detainer andv controller N engaging the rear-face 10, or equivalent abutment means, while the slidedetainer and controller is blocked or locked in this locking position by the grip-operalile or grip-safety member G, if the firing member or hammer should be permitted to move from firing position to fired position through the breaking or wearing away of the ,cocknotch 81er the locking shoulder 17h, the en- ,gagement of the cam face 8k of the firing `fective/contact between the firing member or hammer and the firing-pin P, the slidedetainer and controller N also preventing rearward movement of the main slide and the firing-pin. Grip-compression of the grip-operable or grip-safety member G being relieved, movement ofthe firing member or hammer H from fired position to firing position forces the connecting rod fib downwardly against the compression of the spring 8e, and through engagement of the lower end of the rod 8b with the cupped plunger 8c an outwardly thrusting or bearing force is exerted on the grip-operable or grip-safety member G at substantially the point of pivotal or hinged attachment of the rod G2. to the base portion G of the grip-operable or grip-safety'member G, which force thrusts or moves the grip-operable member or gripsafety member G rearwardlyA into non-comlpressed position or position of safety, and rings the locking-fork 7b thereof into engagement with the bottom-side or bottomface 14 of the slide-detainer and controller main slide against rearward movement, and
